StatAverage (Function)
In french: StatMoyenne
Calculates the arithmetic, geometric or harmonic mean for a series of values.
// Arithmetic mean of the elements in row 1 of a matrix
ResAverage = StatAverage("MyMatrix", statArithmetic, 1 , False)
Syntax
<Result> = StatAverage(<Matrix Name> [, <Type of Mean> [, <Row/Column Number> [, <Row/Column>]]])
<Result>: Real
Mean for the series.
<Matrix Name>: Character string (with quotes)
Name of matrix containing the data, defined by MatCreate.
<Type of Mean>: Optional constant
Specifies the type of mean to calculate:
 statArithmetic(Default value) Arithmetic mean statGeometric Geometric mean statHarmonic Harmonic mean
<Row/Column Number>: Optional integer
Number of the row or column containing the data (1 by default).
<Row/Column>: Optional boolean
• True (by default) if the series of values corresponds to a matrix column,
• False if the series of values corresponds to a matrix row.
Remarks

Number of elements found in a matrix row or in a matrix column

The number of elements found in a matrix row or in a matrix column is taken as a reference. This number of elements corresponds to:
• the total number of matrix rows, returned by MatNbLine (if the calculation is performed on a column),
• the total number of matrix columns, returned by MatNbColumn (if the calculation is performed on a row).
If the series contain less elements than the matrix, the missing values are automatically filled with 0. These values are taken into account during the calculations.

Managing the errors

Caution: StatAverage returns no error code. To find out whether errors have been generated by this function, use StatError. To find out the error details, use ErrorInfo associated with the errMessage constant.
